So years at the track I broke a stock axle, no big surprise it was 40 years old or so... Replaced the axles with Strange axles and today I snapped another one, on the street. Was fooling around and did a half hearted burnout, just enough that it hooked hard and bang... I haven't torn it apart yet but I suspect I twisted it off at the spline as before.
So now I'm torn, do I buy axles again or just bite the bullet and finally put a Dana in this thing.
If I was still employed it'd be a no brainer however I'm on disability since cancer surgery, chemo etc...
Needless to say money is an issue. Considering Dr Diff for a new Dana, anyone have an idea, what the dimensions I need to give him are for a 67 B body, stock width, I do have Caltracs and Mono leafs on the car.
My 8 3/4 has a Detroit Locker but I don't remember how many splines it is I also have no idea how I got the broken stub out before, I know I didn't pull the pig...
This stuff was a lot easier before but these days just cutting my grass kicks my butt so I'm trying to come up with a plan I can actually manage on my own...
Just looking for suggestions, I really just want to replace axles but I also need it to hold up to my stupidity...
67 Coronet 400 Block 500" stroker, 10.8 compression Bulldog heads (yes I'm the guy who bought the only set they sold. Yes I'm know they sold more, at least 1 more set I'm sure... Lol) Cam is ~630 lift, .263 duration MP M1 single plane CRT trans Dynamic converter ~ 3800 stall Det Locker 4.30 gears
Thanks!

How many years did the replacement last? If you get 10 years out a set of shafts is it worth the swap?
Do they make bigger splines for 8.75 axles?

Those 30 spline axles can only take so much. Usually a 3200 pound car will start twisting axles when you get into the 10 second bracket. We replaced our 8 3/4 with a Dana 60 (35 spline) and never had a failure since, car now runs 10.0's at 133 mph.

Just reading the history, this is what I think:
1) axle #1 - old age gets everything 2) axle #2 - stuff happens
I'd put another axle in what you have and motor on, especially with the financial situation you say you are in. Sometimes I think there is a tendency (and I'm not immune to it either) to start replacing major components after a failure when the actual problem was a minor component failure.

Call Strange, they may warranty it. If they say "No" all you're out is a phone call

I bought and used a set of Strange Engr. 35 spline axles and spool in my old pump gas Duster, I also added a steel cap on the driver side for increase strength and proactive to prevent breaking the stock left cap. I had ladder bars with coil overs and that car went low tens a lot before it twisted up that 8 3/4 housing bad enough to rip the welds off of the ladder bar mounts on the passenger side on the starting line I bought a junkyard Dana 60 out of a pickup and had it cut down and reuse those Strange 35 spline axles with a new dana 60 3 seris 35 spline spool, no more problems after that On your deal if you do decide to swap to the 35 spline parts make sure and buy a steel cap and have it installed on the driver side

Some here have said that competition axles don't do well on the street.

No manufacturer will warranty a 30 spline axle against breakage.
Your only other alternative is a 35 spline spool and axles. I know and I'd never ask about a warranty on 12 year old axles anyway... Will be contacting you soon...

I'm about 30 north of the city, so not that far. If you need another pair of hands putting a 60 in drop me a PM. Could burn a Saturday or Sunday.

So I think I'm going to roll the dice on axles again. The Strange shafts I broke were a "Street axle" they sold years ago and I see they have "Alloy induction hardened shafts" that they recommend for street use now.
When I replaced my axles 12 years ago, the new Strange axles were slightly too long and had to cut about 1/2" off the spline.
The housing is all original to the car so I ordered axle lengths to fit a stock housing but if I remember correctly the Locker has a spacer / button in the center between the axle shafts. The original stock axles worked fine with the Locker though,
So is it the "Green Bearings" that caused the issue or did I just get unlucky and get the wrong length shafts the first time?
If "Green Bearings" caused the issue I may go back to tapered bearings.
I'd like to not have to cut the new axles again after I order them...

First comment, you got 12 years out of the Strange axles? Wow, what did you expect to get? I think that is pretty good. Second comment, as to spacers, I thought that when you retrofitted with the 'Green' bearings you removed all of the centering pins as they are no longer needed AND they may preload the bearings. Finally, as an example, with the AMC 20 differential it is common to have to shorten the available axles, Mr. Chop Saw is our friend here. Cutting something off the end is not unheard of.

I'd recommend a set of Moser axles. I've seen a bunch of broken Strange axles.

Not sure about that spacer, was never told it wasn't needed...
